Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

electrodes can vary up to two hundred and fifty-six electrodes. The more electrodes are present‚ the more accurate the result. For this experiment‚ three electrodes were used including the ground and system electrode. The EEG that was carried out in the lab therefore‚ was not as accurate as other EEGs carried out and so errors in results could be due to this.

Experiment 1 Introduction to basic lab equipment and components Introduction: To use an electronics lab‚ it is necessary to become familiar with some typical equipments and components‚ to reduce the accident and damaging the equipments. So the experiment will be accomplished with the right result and everything still in one peace. Objective: • To be familiar and understandings the operation of the basic components and equipments in electronics lab. • To know the color code of the

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer

column‚ 0° C‚ each well had low enzyme activity. In the second column‚ 25° C‚ the results displayed the enzyme actively low as well. In group 5‚ the enzyme was hydrolyzing the starch moderately‚ which is how the enzyme is supposed to react. In the third column‚ 55° C‚ each well displayed the enzyme hydrolyzing the starch at a low pace once again. And lastly‚ the fourth column‚ 85° C‚ the enzyme properly denatured due to the high temperature. Bacterial Amylase’s optimal temperature is 55° C. In the first

Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The

Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due
